It is often convenient to set the center speaker on top of the television set, as shown in the drawing, or it may be placed on a shelf above or below the television or video display. The tweeter of the center speaker should be no more than two feet above or below the tweeters of the main left and right speakers. 5 ­ 6 ft. Models HKB4 and HKB 6 are suitable for use as the side or rear surround speakers in a multichannel home theater system. The two side surround speakers should be placed slightly behind the listening position and, ideally, should face each other and be at a level higher than the listeners' ears. If that is not possible, they may be placed on a wall behind the listening position, facing forward. In a 6. 1- or 7. 1-channel system, in which surround back speakers as well as side surround speakers are used, you may place one pair of speakers to the sides, and a second pair of speakers on the rear wall, facing forward, as shown in the diagram. Experiment with their placement until you hear a diffuse, ambient sound accompanying the main program material heard in the front speakers. Models HKB 4, HKB 6 and HKTW 6 are suitable for placement in the front left and right speaker locations in either a twochannel system or a multichannel home theater system. The front speakers should be placed the same distance from each other as they are from the listening position, and they may be "toed in, " or angled slightly, toward the listening position. They should be placed at the same height as the listeners' ears. SPEAKER PLACEMENT 9 SPEAKER PLACEMENT Powered Subwoofer (HKSUB 12) HKSUB 12 As a general rule, bass response increases as a subwoofer is placed closer to a wall. Therefore, bass output is maximized when the subwoofer is placed in a corner. We recommend that you place the HKSUB 12 along the same wall as the front loudspeakers, as shown in the diagram. Low-frequency sounds are normally omnidirectional, meaning the listener cannot localize them to a specific place in the room. However, frequencies between 75Hz ­ 150Hz can be localized, especially at higher volume levels. Positioning your subwoofer as recommended will provide the most natural soundstage and imaging from your loudspeaker system. Since every listening room is different, Harman Kardon strongly recommends experimenting with the positioning of your subwoofer to obtain the most pleasing results in your room. One technique that can help you find the ideal subwoofer location is to temporarily place the subwoofer near the main listening location. Then move around the room and determine where you hear the most pleasing bass performance. This is the ideal location for the subwoofer. 10 SPEAKER PLACEMENT MOUNTING OPTIONS HKB 4 and HKB 6 Bookshelf Speakers The HKB 4 and HKB 6 speakers may be placed on a shelf. Place the supplied rubber pads on the bottom of each speaker, one pad at each corner, to protect your furniture and the speakers. These two models also feature a threaded insert capable of accepting OmniMount® wall-mount brackets. Harman Kardon recommends that you select Model 20. 0 Wall to safely mount your HKB 4 loudspeakers, and Model 30. 0 Wall to safely mount your HKB 6 loudspeakers. DO NOT mount these speakers from the ceiling, as they are not designed for ceiling mounting, and doing so may present a serious danger to personal safety. [. . . ] the center speaker: Make sure none of the speaker wires are frayed, cut, punctured or touching other wires or terminals, which may cause a short. · If your receiver/processor is set in Dolby* Pro Logic* mode, make sure the center speaker is not in phantom mode. · If your receiver/processor is set in one of the Dolby Digital or DTS® modes, make sure the receiver/processor is configured so that the center speaker is enabled. If the system plays at low · Check all wires and connections between receiver/amplifier and speakers. [. . . ]
